Gentle Metabolism 2.1.0-beta.1 — Minecraft 1.21.1

Beta release · Fabric only · 2026-10-16

Requires Minecraft 1.21.1, Java 21 or newer, Fabric Loader 0.16.10 or newer, and matching Fabric API 0.115.6+1.21.1 or newer. Install on both the server and every player's client.

Changes

• Adds hinged toilet lids, persistent grime and visible sanitation feedback.
• Adds a 128-use cleaning brush, 16-use paper roll and reusable 64-unit collection bag, with recipes and original item sprites.
• Paper is spent only after successful solid toilet use. Cleaning preserves stored contents; partial transfers keep any remainder safely in its source.
• Adds the seventh illustrated guide chapter and updates lid, cleaning and offhand controls.
• Includes the complete thirst, digestion, diarrhea, water-purification, outdoor-waste, toilet and compost-to-crop loop, with rebindable controls and English/Simplified Chinese text.
• Fixes lid-closing hit detection using a reachable in-block click area, verified with real raycasts and graphical-client mouse interaction.

Verification and cautions

24 unit tests and 55 real Minecraft GameTests passed for this build. The remapped release JAR was checked in a graphical client and a dedicated server, including saving and reopening worlds. These checks do not guarantee long-running multiplayer or all modpacks and protection plugins.

Back up your world and configuration. Replace the old mod JAR rather than keeping both. Old 2.0 toilet storage is retained; old toilets begin with no grime. Existing configuration values are preserved. Do not downgrade a Minecraft 1.21.1 world to 1.20.1.

中文：新增可开合马桶盖、持久污渍、128次清洁刷、16张纸卷、64份收集袋与第七章手册；修正实际鼠标合盖判定。此构建通过24项单元测试与55项真实GameTests，并完成真实图形客户端和专用服务器存档重启检查。仍为beta，请先备份并在测试世界体验，服务端和所有客户端均需安装对应版本。
